To 0]/- /ff/mmf if mfr/'U conm/'Prizm Be it known that we, l IENRY Josiin Po ,iiLnsii and FasL-l llimA PonLnsAic, citizens v of the United. Sta-les county of Cook; Stute of Illinois, and Morristown, county of Morris, Stato of New Jersey, respectively, have invented certain new and useful vliiiproveineiits iii Fucil-lleediiig- De` vices for .liuemol-Combustion Motors, of which the following is a clear and precise dosoiiption, reference lacing had 'to the several vie-ws of the. accoiiipaiiyinpi drawings.

(')ur invention relates lo improvements iii internal eomliuslion liydro-carlioii motors, the object heilig,l` to provide moans for positively feeding' the requisito quantity of fuel for each charge and to prevent feeding any excess of fuel for the charges.

lith our fuel feeding devices, we are` enk ahled to positively feed the requisite quantity of fuel regardless of the spoed of the inotor, the degree of suction, or tho length of time the fuel feeding outlet kept open, Without danger `of flooding toc iriotor with fuel, or not feeding enough o fuel.

Our device can be used with stationary and portable niotors of ei or the foiir-cyele type.

To attain the' advantages set forth We so construct our device as to first supply fuel, from a reservoir, into a fuel rece taole of a pioi'leteriiiinod. capacity, .then to s iut off the supply of fuel to the reoeptaole', and there` ,after to discharge the, requisite. quantity of fuel from the receptaole'into the charge of air, the supply of fuel remaining shut ol throughout the period of feeding disoharging fuel'iiito the charge of air, as will loo clearly shown in the following description, reference losing had to the several drawings in Wliioh:

Figure- 1 .is a vertioal view, partly sectional, of a forni of our device especially adapted to feed crude oils, ina forni' of spray, into the vaporizing chamber, as the charge of air is drawn through there. Fig. 2 shows this forni attached to a motor w'.iimfided with a throti'ifliiig type of governor tion, but this forni may be used with motors using the liit-or-niiss mods 0f speed regulation equally Well. Fig. 3 is a vertical View, paruly sectional, of a forni especially adapted to vehicle motors, such as automobile, niarino, and. traction motors. This forni is similar to that of Fig. i,

ther the two-cycle lor speed regula4 and residing@r at Chicago,

feeding outlet is normally kept elosed, to prevent spilling of fuel, and-is opened onlyv at the time. of feeding. Fig. 4 is a vertical sectional view of a forni in which the fuel is discharged l from the receptacle by air pressure, Fig. 5

energia that the-fuel i the force-d shows a device attached to a motor provided i with a hit-or-iiiiss typo of speed governor.

vln the several drawings the similarly functioned principal parts are designated by the Referring to Fig. l, lr'is a hollow shell or casing, provided with an air intake 10, a valve seat for air valve 11, a mixing or coinlius'tion eliamliei c which communicates with the cylinder of the engine through the opening vlllthin this easing cis also a hollow chamber m, partly filled with fuel, in which is a fuel receptacle 5, of a suitable determined capacity. The fuel inlet l serves to afford communication between the fuel receptacle 5, and the fuel reservoir m for the purpose of filling, the receptacle with fuel from m. The piston or plunger` 7 serves, liy its reci rocating niove yients, to open a'nl'l sluit t ie inlet l and overflow outlet 2 a id to force the requisite quantity of fuel lfroi receptacle 5, through fuel feed outlet 4. and the atomizing nozzle 40. The fuel is supplied through a and surplus is drained back to fuel tank hy. pipe 3. ,i

"ilic, operation is as follows: The reservoir m being filled with fuel and the plunger in its normal position as shown, the 'cavity'. or cylinder, 5 will be nlled through opening l, then, upon the movement of the plunger 7, through movement of valve rod 37, the plunger, moving to the loft, Fig. l, will pass over inlet l and overflow outlet 2 and cover them, shutting O' the egress and ingress of hiel from m to 5. Upon further movement of the plunger, a greater part of the fuel, con 95 tained in t le cylindrical, receptacle, will he out through nozzle 40, into the charge of air entering through 10, lt Will be notioed that a certain quantity of fuel is thus isolated from the main supply and thereafter a'desired part of this isolated quantity of fuel is discharged or fed into the ohaie of air,L and that during this feeding perioll no fur-l ther` supply 'or addition of fuel can enter the receptacle 5. Upon the return movement of valve rod 37 the plunv'er 7 is brought back to its normal position liyspring 19, opening inlet l and overflow outlet 2, thus roo of our device to throttling mode of speed reg.

ulation, the governor in this caseV being arranged to'throttle the charge of airby increasing or decreasing the size of the air pas sage, and correspondingly increase or decrease the travel or movement of the plun ger, 7, by lowering or raising the wedgey bloeli 34, respectively; as will be apparent',

v the longer the travel of the plunger 7, after' the egress of fuel through 7, has been closed,

the more fuel will be discharged out lof the receptacle 5. The extent of the movement of plunger 7 is further augmented by the adjustments of detent With motors using the hit-or-miss mode of speed regulation the adjustment for the propel' length of travel of the plunger 5 is effected by the setting of this detent 35. Fig. 2 shows this form of the device attached to a motor provided with a throttlingl type of governor.

Fig. 3 shows a form that is especially adaptable t'o motors'used for propelling vehicles or such motors that are apt to be rocked while working. ln this form the fuel receptacle 5 is provided with fuel inlet l, overflow outlet 2, and fuel feed outlet at, this latter terminating in a valve seat and is held normally closed by a valve, to prevent spilling of fuel through 4 on excessive rocking or jarring. The arrangement for varying the throw of the plunger 7 differs in form from that shown in Fig. 2 but the voperation is same in effect.

Fig. 4 shows a form wherein the plunger 7 serves principally as a valve for opening and closing the fuel inlet l, and for admitting and shutting off air pressure to and from thereeeptacle 5, assisting in the feeding to a slight degree only. The. extreme in movement of this plunger 1, is adjusted so that the opening di through this plunger will come opposite opening d and thus form a continuous passage for air under pressure, from pipe S, throughkl, d and d2 and into receptacle 5; 'when air, under pressure, is thus admitted it will force out the fuel from receptacle 5 through fuel feed outlet 4; the fuel inlet l al ways being closedbefore the continuous passage between Sand 5 is established, the fuel in receptacle 5 has no other path to get out except feed outlet 4. The adjustment of capacity of 5 for requisite quantity of fuel for the charges is effected by screw 6. This form, as shown, is adapted to motors using the hit-or-miss mode of speed regulation.

F1g. 5 shows` our device attached to a motor using the lut-or-miss mode of speed regulation, the governor being arranged to raise,

by means of levers and connections, when the speed exceeds normal, the hinged hook n high enough to engage the lip Lnvith collar r and thus prevent the plunger-7 from returning to its normalposition, and as no fuel can enter the receptacle 5 unless the plunger is in its normal position, charges of fuel will be missed until the speed becomes normal when the governor will lower the hook, releasing the collar andthus allowing the plunger 7 to return to its normal position, when a charge of fuel will be admitted.

It will be noted that in our device we provide a receptacle of such capacity as will hold the largest quantity necessary for a full charge, that we fill this receptacle with fuel, and then isolate, so to speak, the fuel con* tained in the receptacle, to prevent any fur-v ternal combustion motors, of a fuel recepta cle, provided with fuel feed inlet, overflow outlet, fuel feed outlet, and'adapted to contain a. predetermined quantity of fuel; a fuel reservoir adapted to supply fuel to said receptacle through said inlet; nieans for openin g and closing said inlet and said overflow outlet at predetermined intervals; and means for forcibly discharging a predetermined quantity of fuel from said receptacle through said fuel feed outlet when the said inlet and said overflow outlet are closed.

2. A casing, provided with an air passage, communicating with the combustion chamber of an internal combustion motor, a fuel receptacle, of asuitably determined capacity,

and provided with fuel feed inlet, overflow' outlet and fuel feed outlet, said feed outlet communicating with said air passage g a fuel reservoir adapted to supply fuel to said receptacle through said inlet 5 means for openmg and closing alternately and at predetermined intervals said inlet and said overflow outlet; means for forcibly feeding a predetermined quantity of fuel from the receptacle and through said feed outlet at the interval when said inletand said overflow outlet are closed. f

3.
